Do you think they're trying to put preasure on me to leave the house?

I live with my eldest brother and his family since I was 11 his wife was putting preasure on me to leave the house but I didn't have anywhere else to go.. Lately he told his wife to cook food only late at night (by 23 PM to 00 AM) claiming that the reason for this is that the cats eats the meats and they can't help it to stop them. My brother and his wife knows that I'm always asleep at that time so do you that they do this on purpose to keep me hungry and uncomfortable ?
